The flashpoint and boiling point determine the category of a flammable liquid. Flashpoint is the minimum temperature at which a liquid gives off enough vapor to form an ignitable mixture with air near the surface of the liquid. A flammable liquid is any liquid having a flashpoint at or below 199.4Â°F (93 Â°C). Flammable liquids are divided into four categories: Category 1: Liquids with flashpoints below 73.4Â°F (23Â°C) and boiling points at or below 95Â°F (35Â°C) (1910.106(a)(19)(i)). Examples: acetaldehyde and ethyl ether.
